TROLLEY-WHEEL.

To a/ZZ whom, it may concern:

v Be it known that I, GEORGE W. JOEE, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Trolley-Wheels, of which the following is a specification. 1

This invention relates to trolley-wheels, and has for its objects to produce acomparatively simple eilicient device of this character which in practice will 'during its vtravel upon be securely engaged with the trolley-wire, thus to wholly obviate liability of the wheel accidentally leaving the wire, one wherein the wire-engaging members will be moved automatically to wire engaging and releasing position during travel lof the wheel7 and one in which the trolley may when circumstances require be readily released from the wire.

'With these and other objects in view the invention comprises `the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of atrolley embodying the invention. Fig. 2 is a central section through the trolley, takenon the line 2 2 of Fig. 3. Fig. 3 is a transverse'sectional elevation taken on the line 3 3 of Fig. 1 Fig. 4 is a detail perspective view of one of the actuating members. Fig. 5'is a similar view of one of thewire-engaging members.

Referring to the drawings, 1 designates a trolley-pole having the usual fork 2, provided.

with a transverse shaft 3, having rctatively mounted thereon a trolley-wheel 4,' there be ing provided on the shaft'bearing-cones 5,

which, together with antifriction-balls 6,

housed in ball-casings 7, permit free antifric-v tion movement of the wheel upon the shaft. rEhe body 4 of the wheel, which is housed withina casing S, is made up of a pair of sections.

9, `detachably connected by bolts 1Q, said body 4 being ,provided with a peripheral groove or channel 1.?1, designed to receive the stems or Shanks 12 of wire-engaging members 13. The members 13, which are pivoted upon-pintles or axles 14, preferably in the form of continuous rings extending around and maintained flXedly within the groove 11, are arranged in Aoppositely-disposed pairs, having ,upon their inner faces semicircular recesses 15, which conjointly form a circular opening or seat 16 for the reception of the trolley-wire 17, while the outer ends of the pairs of engaging members beyond the re- Specication of Letters Patent;

cesses 415 are reversely curved to permit ready entrance yof the wire into the opening 16 and have upon their outer side faces oppo.-l

'around the periphery of the wheel and that these members are protected by an outer casing 21, composed of sheet metal and having on its opposite sections inturned reverselycurved flanges 22, which'serve as guides for directing the wire between the curved faces of the engaging members and thence to the opening or seat 16.

Pivotally suspended upon the shaft 3 is Va `substantially U-shaped member or frame 23,

which straddles the trolley and ismaintained in a normally vertical position by means of a weight 241, there being carried by the side portions or arms of the frame actuating inembers 25, preferably in the form of upwardly and inwardly inclined arms provided at their upper ends with cam-heads 26, with the ii1 ner curved faces of which the projecting portions or faces 18 ofthe engaging members13i contact for moving vthe members 13 to wireengaging position, it being apparent that the members 13 at the upper end of the vertical diameter of the wheel 'will alone be held in such engagement by the cams, whereby the Wheel will ride freely upon the wire and at the same time be maintained in engagement therewith and to prevent accidental escape therefrom.

Projecting outwardly and rearwardly from theweighted portion 24 of the cam-carrying frame is an arm 27, perforated for the'nttaehment of a cord or analogous element (not shown) whereby 'the frame may when circumstances require be moved from its vert-ical position and the heads 26 be thus brought to a point at which the engaging members will be acted upon prior to reachingthe wire, to thus prevent engagement of the wire by trolley and permit of the latter being released from the former. ,A

ln practice, supposing the parts tobe in normal position, Ias the wheel Il revolves the pairof engaging members 13 in passing between the normally vertical actuating mem- IOO bers will be acted upon by the cams 26,

and thus move to engaging position, as

shown at the to of Fig. 3, to thus prevent escape of the tro ley from the wire and at the 'members will be engaged at onetime with When it is desired to` same time compressing the spring 2Q, dis-l osed between the members. ers 13 move beyond.l the influence of vthe cams 26 the springs 2() will ex and, thu-s' opening the pairs of members re atively, as

shown at the lower portion of Fig. 3, for releasing the wire, it being consequently understood that only one l,pair of the engaging the trolley wire. wholly release the trolley from the wire, the

`frame 23 is' swung upon its pivot in the direc- I' tion indicated by the arrow in Fig. 1 through 'understood that in attaining these ends vari'- ous changes in the details of construction herein set forth may be resorted to without de arting from the spirit of the invention.
